What he said. Unless you're going digital where you can tweak till you're blue in the face, just picking drivers and running isn't the way to go.

That said, I would look at the Dayton RS series drivers with that "tweeter" - perhaps the 8". And you may need to add on the top end as well - depends on your ears. The closer to the minimum/maximum recommended range of the drivers you go, the steeper the topology you'll need. But, this really isn't a first project. Probably not a second project.

There are drivers that are specifically designed for in wall use which don't need a box. If I was doing it I'd come up with something a little more original than the grills they use. I don't like that almost stealthy look of the white grill covers. For built in I'd say go with an infinite baffle sub too.

Should use? No.

What's your budget, what're your requirements... we can pick stuff that fits, but that only barely gets you going on things. And everyone is going to have a different opinion on what way might be the best way to go.

In wall means you don't have baffle step to deal with. If you don't build boxes and mount them in-wall, you're looking for drivers that meet your needs in a sealed box.

Beyond that, the first couple questions will drive the rest of suggestions.
